Chapter 24. X Window System Environment

libxcb-1.12

Introduction to libxcb

The libxcb package provides an
interface to the X Window System protocol, which replaces the
current Xlib interface. Xlib can also use XCB as a transport layer,
allowing software to make requests and receive responses with both.

This package is known to build and work properly using an LFS-8.2
platform.
